I 'lkpplication filed. January 8, 1903. Serial No. 138,210.

To all whom it may concern:

Be it known that I, EDWARD F. SMITH, of

Rochester, in the county of Monroe and State of New York, have inventedcertain new and useful Improvements in Slicing- Machines; and I dohereby declare the following to be a full, clear, and exact descriptionof the same, reference being had to the accompanying drawings, forming apart of this specification, and to the reference-numerals markedthereon.

My present invention has for its object to provide a machine for slicingmeat, bread and similar material and it embodies generally a support orholder and a reciprocatory carriage having mounted thereon acontinuously operated rotary cutter and means for operating it andreciprocating the carriage whereby a draw out is effected.

My invention also has for its object to provide means for adjusting themovement of the carriage relatively to the movement of the cuttingportion of the knife whereby a greater or lesser portion of the blademay be moved in contact with the material, depending upon the naturethereof and to these and other ends my invention consists in certainimprovements and combinations of parts all as will be fully describedand the novel features pointed outin the claims at the end of thespecification.

In the drawings: Figure 1 is a top plan view of a slicing machineconstructed in accordance with my invention. Fig. 2 is an end elevationthereof showing the parts at the beginning of the slicing operation.Fig. 3 is a similar view showing the parts at the completion of saidoperation. Fig. 4 is a rear elevation shown partly in section. Fig. 5 isa horizontal sectional view taken on the line AA of Fi 2. Fi 6 is avertical sectional view t rough the cutting knife taken on the line C-Oof Fig. 2. Fig. 7 is a detail sectional view on the line DD of Fig. 2showing the sharpening device. Fig. 8 is a detail sectional view on theline E-E of Fig. 2.

Similar reference numerals in the several figures indicate similarparts.

A slicing machine constructed in accordance with my invention embodiesa-supporting frame or holder a which may be conveniently mounted u on atable or other support or mounted as s own, upon suitable downwardlyextending legs I). At one side 1 of the frame isprovided a trough orreceptacle, adapted to contain the material to be sliced, which isformed by vertically extending sides '0. The material to be operatedupon, such as bread or meat is conveniently operated toward the cuttingknife by hand although it will be understood any suitable means may beemployed for this purpose and in order to hold it firmly during theslicing operation I form the bottom of the trough at a slight angle to ahorizontal plane, at its outer or forward end, as shown particularly inFig. 4 so that the material supported thereon will be naturally crowdedagainst the outer wall 0 of the trough. To this end I also arrange amovable guard frame provided with the top and side adapted to engage thecorresponding portions of the material and which are movable relativelyto both the bottom and side of the trough. This frame or presser may beformed in a variety of ways but the construction which I deem preferableis that, shown in Figs. 1 and 4, in which it is provided with its up orand lower ends 20 and 21 respectively gui ed in apertures formed in theholder at and wall 0 and having at its side an outwardly and upwardlyextending arm or guide '5 provided with a slot through which extends apin upon a suitable bracket whereby the frame may be adjusted relativelyto the side and bottom of the holder to accommodate both small and largepieces of material.

At the center or angle portion of the guard frame is provided the flange22 flaring outwardly, in the direction from which the material isadvanced, so that as irregularities of the material engage therewith theguard will be raised and lowered and the frame held in .contact with thematerial at all times preventing the operators fingers from accidentalcontact with the cutting knife. If the operator desires he mayconveniently remove the frame by tilting it to the position shown indotted lines in Fig. 4.

At the forward end of the support or holder a is a vertically extendingsupplemental frame 7c, provided at its upper and lower sides with waysZ, upon which is movably mounted a reciprocatory and transverselymovable carriage m movably secured to the frame it by means of clampingpieces a adapted to engage over the guides, as shown in Figs. 4 and 6.Arranged on the carriage is a relatively stationary stop plate 0 adaptedto be engaged by the material to be sliced and, pivotally mountedin rearof said stop plate is a rotary cutting knife'p, having the over hangingcutting portion or edge (1 arranged in the plane of the stop plate, asshown in Figs. 5 and 7, and as a convenient means of construction Imount the cutter upon a stud 11 attached to the plate. The rotary and reciprocatory motion of the cutter and carriage respectively isaccomplished by a single 0 erating means as'will be further described.'I 1e "rotary motion'of the cutter is imparted to. it by; means of; asmall pinion s rigidly se'cured' thereto and meshing with the teeth of;an internal gear formed. on the plate or disk t; pivotally journaledupon a studu secured to an arm 12 on the reciprocatory carrFiageetending in rear of the stop plate, (see w indicates an arm attached tothe carriage andto the stop plateo tostrengthen the latter, saidarmbeing off set as willbe understoodto accommodate the overhanging edgeof;.the knife or cutter.

' The disk t constituting a driving wheel, is adapted to be rotatedxby ahandle a: which is attachedto a wrist pin y, and also j ournaled on'thelatter is a radius. arm or link 2, the outer endof which is pivotallyattached to a lug or extension 10 on the frame is so that. as thedrivingwheel'isv operatedby the movement of..the handle, a reciprocatorymotion will be imparted to the carriage. In order that the distancethrough which the carriage is m'oved,'at each revolution of the crankhandle. may be adjusted to accommodate it to the nature ofthe materialto be operated upon, I provide 'means for" adjusting the wrist pin 'yrelatively to the journal a of the driving wheel. have shown the Wrist:pin arrangedupon a plate 2fwhich is secured. to the'diskt by means ofscrews. or bolts 3 which latter may bei'readily removed and inserted inother threadedrapertures (as shownin dotted lines in" Fig. 3).toincrease the diameter of the circle described by the rotation of the pinthereby causing the carriage to be operated through greater or lessdistance as may be required by the nature of the material-operatedupon.

For instance in operating upon a small piece ofirelatively hard materialthe Wrist pin is arranged near the center of rotation and therotary-movement of .the cutting'edge willbe the same while the amount,of reciprocation of. the carriage willjb'e shorter.

Arranged at the forward endof the carriage m is a gage plate 4 which isadapted to be normally in line with the forwardor open endof the troughandin order that the thickness ofthe slices of materialto be removed,

may-be varied, I provide said gage plate with a ing threadedlugs or ears7 engagedby an In the present; instance 1' adjusting screw 8, by meansof which the gage plate may be moved relatively to the plane ofthe'l'rnife or cutter.

As a convenient means for sharpening the rotary knife g I have providedat the upper side of the frame m ears or lugs between which are pivotedarms 11 carrying at their outerends a piece of abrasive material,indicated by 12, which is adapted to engage the edge of the knife, asshown in full lines in Figs. 2 and 7. The arms 11 are attached to a hub,as shown, having flattened or angular surfaces 13 and 1 1 against whichengages a spring-operated finger 50, said surfaces being so arrangedthat when the block is. moved into the operative position it will beheld yieldingly in contact with the edge of the knife, during therotation of..the latter, andwhen the finger 50. is in engagement withthe face 1.4. the device will be s'upportedin the opera tive position,as shown in dotted lines in Fig. 7;. 'ihegrinding device beingmounted-upon the carriage it: may be moved into contact therewith andemployedto sharpen the knife during a slicing operation.

The'operation of the machine will now be understood. The material to beout, such as shown in fulllines in Fig. 1 and in dotted lines in Fig. 5,is placed in the trough or holder between the side plates 0 and it ismoved into engagement. with the gage plate twhich may be adj'ustedtodetermine the thickness of the slice. The operator revolving the handle'96 moves the carriage m from the position shown in Figs. 1. and, 2tothat. shown in Fig. 3. This occurs simultaneously with the rotation ofthe knife, through the operation ofthe pinion s and the contacttherewith theslice is all'owedto fall .away from the machine into anysuitable receptacle. The continued rotation of'the .handle causes thecarriage to be retracted .allowmg the material to be again moved intocontact with the gage plate and an additionalslice to be cut therefrom.
